One of California's Toughest Gravel Races | Tour de Big Bear Raw & Uncut

First time taking on the Tour de Big Bear Gravel edition. The dirt part was definitely not easy. It was not gravel but deep sand that seem to get deeper as you progress. I have to say changing my front tire to the Thunder Burt 2.1 was the best decision as it help tremendously. I was running 25 PSI in the front and 28 in the back. Have you done this race ? What would you have done differently?
